2) Put files within subdirectories like putting documents in
folders.
3) Put subdirectories within subdirectories like putting
folders within folders.
Pathname
The name of the directory combined with the names of one or
more subdirectories is called a pathname. Volume names and
subdirectory names are preceded by a slash, “1”. (Note that some
applications add the slash for you.) For example, you could have
a volume named
/MY . DISK and a file called NY. FILE on the
root directory of that disk. To access that file, you would use the
pathname
/MY.DISK/MY.FILE. You could also have a file
JUL . AUG in a subdirectory (folder) called PHONE on a disk called
/BILLS. To access that file, you would use the pathname
/BILLS/PHONE/JUL DEC. Refer to the diagram below.

ProDOS Directory Structure
Now when an application asks you for the pathname of a file,
you’ll have a basic understanding of what it expects.
System Files
A system file is a ProDOS file that starts an application.
Typically, these files have the suffix
. SYSTEM (e.g.
/APLWORKS . SYSTEM, /ACCOUNT. SYSTEM [see above], etc.). When
you boot ProDOS, it runs the first system file listed in its
directory. So, if BASIC.SYSTEM is the first system file on your
ProDOS boot disk, ProDOS will boot and then put you in BASIC.
